BSEN 10151 (strip) and BSEN 10272-3 (wire) for springs are outlined. The grades in each standard are tabulated and compared to the BS5770-4 and BS2056 which they replace, where grades such as 301S21 301S81 302S26 302S25 and 305S11 were specified. Grades listed include 1.4016 1.4021 1.4028 1.4031 1.4568 (17/7 PH type) 1.4310 1.4301 1.4401 1.4369 1.4372 and 1.4568 Mechanical properties in the cold worked (temper rolled for strip, drawn for wire) conditions are shown. Heat treated properties for precipitation hardening grade 1.4568 wire are also shown.

BSENISO 3506 replaces BS6105. Part 1 covers bolts, screw and studs, part 2 nuts and part 4 tapping screws. The chemical compositions are common to the various parts. Austenitic grades A1 A2 and A4 are shown and compared to bar grades 303 304 349S17 316 and 394S17. Mechanical properties for property class 50 70 and 80 austenitic bolts and studs and property class 20H 25H 30H and 40H tapping screws are tabulated and the fastener designations, such as A2-70 and A4-25H described. Duplex FA (ferritic-austenitic similar to 1.4462 (2205) of EN 10088-1) is a likely future grade for inclusion in the standard. Fastener grade selection is covered in annexes to the standards. The standards lists grades 1.4439 1.4539 (904L) 1.4529 (6% molybdenum austenitic) and 1.4462 (2205) as suitable for reducing the risk of chloride induced stress corrosion cracking failures in applications such as indoor swimming pools.

This article describes what types of structural stainless steel sections are available and how they can be procured. It outlines what sections are available ex-stock and which may need to be made-to-order. Ranges of dimensions for hollow and bar sections are given.

Stay Bright traces the story of the development, production and use of high chromium stainless, corrosion and heat resisting steels in Britain.

Stay Bright chronicles the fortunes of the British companies manufacturing stainless steels; it tracks international alliances and rivalries and charts the history through times of economic boom and recession. It follows the twists of fate of those involved through world war, cold war, nationalisation and the impact of globalised industrial manufacturing.

Few materials can claim to have made such an impact on modern life; this is how they did it in Britain.

Flat products ( plate sheet coil and strip ) tolerance standards are outlined. These include EN10029 EN10048 EN10051 EN10258 and EN10259. Thickness, width length, flatness, out of square and edge camber tolerances to EN10259 are discussed along with the advantages of the EN tolerance standards. Notes for ordering stainless steel using EN10259 to standards EN10088 part 2 EN10095 EN10302 and EN10028 part 7 are also included.
